This invention presents an electronically configurable architecture where the plurality of photovoltaic panels can be connected to deliver the maximum power output. This architecture provides maximum power point to the maximum number of photovoltaic panels by connecting them in parallel. Under-rated panels are dynamically coupled with over-rated or maximum-rated panels in a series-connected architecture to utilize the under rated power in the final delivery. Notable efficiency improvements may be observed in contrast to the prevailing optimization with minimum power drop out architecture. The architectural modifications are proposed with bi-stable electromagnetic changeover contacts to minimize the power dissipation in control side. Moreover the rearrangement in connection architecture is proposed to be communicated on instance and regular basis through SMS and SPI protocol for easy fault diagnosis by the service personnel from the proposed data mining firmware.

A three-position disconnector switch includes a platform, a power in contact, a power out contact, an earthing contact, and a piston. In a first position, the piston contacts the power out contact and the power in contact. In a second position, the piston contacts the power out contact. In a third position, the piston contacts the power out contact and the earthing contact. The piston moves along an axis to transition between the different switch positions. The power in contact is mounted to the platform, the power out contact is mounted to the platform, and the earthing contact is mounted to the platform.

A safety switch with fool-proof function and a toaster with the same are provided. The switch includes two pairs of first contacts connected to a live wire, a pair of second contacts connected to a zero line, and a trigger structure. The two pairs of first: contacts are connected in series in a power circuit. A trigger gap is formed between the first contacts and the second contacts. The trigger structure is movable up and down to drive a pressing part out of and into the trigger gap. When the pressing part enters the trigger gap, the two pairs of first contacts are electrically connected respectively. Thus, the power circuit can be effectively turned off through the switch, thereby improving the safety performance. Moreover, the switch adopts a mechanical contact structure, which is not affected by high temperature and other electromagnetic interference signals, and has high safety.
